“…However, phosphoric acid etching causes a greater degree of enamel loss 14) . Hashimoto et al 37) , evaluating the erosion of BO and TX on enamel by atomic force microscopy, observed that TX increased the porosity of the enamel surface and significantly increased the enamel loss. Scougall-Vilchis et al 18,23,26) reported that in scanning electron microscopy (SEM) images of the enamel surface morphology, BO induced more conservative effects than did the acid-etching system.…”

This in vitro study compared the shear bond strength (SBS) and adhesive remnant index (ARI) of two systems for bonding orthodontic brackets to enamel. The first system involved a self-etching primer (Beauty Ortho Bond, BO) containing surface pre-reacted glass filler. The second involved a primer applied with phosphoric acid etching (Transbond XT, TX). Ninety-six extracted human premolars were divided into eight groups: Group I (TX/direct bonding), Group II (TX/indirect bonding), Group III (BO/direct bonding), and Group IV (BO/indirect bonding). Groups V-VIII were identical to Groups I-IV, respectively, but were also subjected to 1,500 thermal cycles between 5 and 55°C. ARI was scored by binocular microscopy. SBS was analyzed by three-way ANOVA and the Bonferroni test. ARI was analyzed by the chi-squared test. The BO groups showed lower SBS and ARI results than the TX groups. SBS was significantly influenced by the primer material, bonding technique, and thermal cycling.

Reduced friction and wear of materials after the use of the carbon nanomaterials including nanodiamonds (NDs) have been confirmed by several studies in material engineering. Mechanical cleaning of the tooth surface by brush bristles should leave as little tissue roughened as possible. Higher surface roughness increases the tissue's wear and encourages the redeposition of the bacteria and the colouring agents present in the diet. Therefore, we evaluated the tooth tissues' surface's morphological changes after brushing them with the NDs suspension. Ten human teeth were brushed with the NDs aqueous suspension. The surfaces were observed using an Atomic Force Microscope (AFM). We found that the nature of the tissue surface became milder and smoother. A number of selected profilometric parameters were compared before and after brushing. We observed that brushing with the suspension of NDs resulted in a significant reduction in the enamel and dentine's surface roughness both in the range of the average parameters (Ra; p-0,0019) and in the detailed parameters (Rsk; p-0,048 and Rku; p-0,036). We concluded that the NDs used in the oral hygiene applications have a potentially protective effect on the enamel and the dentine's surfaces.

“…The erosion effects are different compared to the acidity of treating agents (acid, adhesives, etc.) and are related with clinical effects [58]. Surface hardness of enamel may be determined on AFM images based on the curve of cantilever force [59,60].…”

Bearing in mind that in the field of jaw orthopedics and related scientific fields, there are no scientific studies that use the most modern technology based on the Atomic Force Microscopy (AFM) to investigate the nanostructure of tooth enamel after etching with 37% orthophosphoric acid, in this paper we will use this method, which is currently the most reliable, to determine the degree of tooth damage after its etching in the process of fixing orthodontic brackets. Considering the fact that the degree of enamel damage after etching cannot be realistically comprehended by the method called ’network’, because in this way the damage cannot be seen three dimensionally (the depth of the damage), but only the damage in a single plane, a more precise analysis can be obtained with the application of the most contemporary method that we can apply in this case, and that is the application of AFM technology.
